Description

In order to enhance compile-time robustness, it is proposed to parameterize the "CurveFitter" class with the type of the function to be used for the fit, i.e.:

public class CurveFitter<T extends ParametricUnivariateFunction> {
    // ...

    public double[] fit(T f, final double[] initialGuess) {
        // ...
    }

}

Thus enforcing that instances of subclasses like "PolynomialFitter" defined as

public class PolynomialFitter extends CurveFitter<PolynomialFunction.Parametric> {
    // ...
}

cannot call the "fit" method with a different function argument.
